Title: Edge-guide device for sewing machine - uses guide plates with internal air-jets to control fabric
Inventor: HANNEMANN FRANZ
IPC: D05B35/10
Filed: 1979-10-26
Abstract: A guiding device for a sewing machine comprises a pair of parallel, similarly-constructed plates between which the workpiece is fed to the needle. In the inner face of each plate is a jet orifice which produces a stream of air directed towards the guide edge, and urging the workpiece into contact with it. The air jet is situated at the apex of a triangular recess in the inner face of the plate, the base of the triangle being adjacent, and parallel to, the guide edge. The workpiece encloses the open side of the recess, forming an expansion nozzle for the air-stream, which produces a suction effect keeping the fabric edge against the guide edge. The device endures a seam is parallel to the fabric edge. This construction facilitates the handling of the workpiece, and is less complicated than the original design.

Title: Fibre matting mfr. - has structured gas-fibre flow path to perforated conveyor building up fibre deposits
Inventor: MUSCHELKNAUTZ EDGAR PROF DR IN
IPC: D04H1/4218
Filed: 1980-06-20
Abstract: The perforated conveyor belt forms an angle of 90-150 deg., pref. 100-120 deg., with the direction of gas flow which carries the organic or inorganic fibres to form the matting, at the gas channel outlet. A curved guide acts as an extension of the gas channel on one side, in the direction of the conveyor, to apply a Coanda effect on the gas flow and deflect it towards the conveyor and carry air or recirculating gas with it from the ambient atmos. Atmospheric air flows between the lower edge of the gas channel and the conveyor at an angle of 45-90 deg. to the direction of gas flow, at the gas channel outlet, and in the direction of conveyor movement towards the fibre laying zone. The gas flow, carrying the fibres, follows an S-shaped path with two deflecting points towards the conveyor to give the suction effect on the whole flow action. The flow direction changes by 0-30 deg., towards the conveyor at each deflecting point. Designed for thermal insulation applicns., the process gives a matting with a constant density of randomly dispersed fibres.

Title: Castor, in particular self-locking swivelling castor
IPC: B60B33/00
Filed: 1981-01-27
Abstract: The castor is in particular a swivelling castor, intended as a chair castor with a castor holder and a running wheel whose wheel axle is mounted at its ends with the aid of leaf spring legs in the wheel fork or the wheel housing. The invention is based on the object of simplifying the assembly and, when desired, disassembly of the running wheel of the castor and of making its manufacture more economical. The invention achieves this object by means of a special design of the sprung legs, with the aid of which the wheel axle of the running wheel is mounted in the wheel fork, in such a way that they also assume the function of engagable and disengagable securing bars for protecting against the running wheel dropping out. With a simple basic shape of the invention, the free ends (10) of the leaf spring legs (4) have a laterally sprung holding ring (12) which releasably embraces the end (3) of the wheel axle and, as a result, protects the running wheel (2) against dropping out and which can be pressed to the side for the purpose of the assembly or disassembly of the wheel axle (1). In a further development of the invention, the wheel axle (1) of the running wheel (2) is mounted at its ends (3) in a leaf spring bracket (6) which functions as holding and braking spring and whose sprung legs (4) are constructed at their free ends (10) as a sprung snap-in closure and, for this purpose, have a punch-out (14) whose contour forms a bearing recess (11) for the end (3) of the wheel axle and a laterally sprung holding ring (12) which surrounds and secures the end (3) of the wheel axle. <IMAGE>

Inventor: SHIMAI HIDEO
IPC: A44B19/58
Filed: 1981-04-29
Abstract: A device for producing a region which is free of interlocking members in two continuous slide fastener stringer tapes is described. Provided in the device is a support table which has a guide groove for receiving the two stringer tapes along a straight path. Two guide plates are arranged on each side of the guide groove and extend over the latter towards one another in order, together with the guide groove, to bound a guide channel. A pressure pad is vertically movable around a swage arranged in a stationary manner in the support table in order, together with the guide plates, to clamp two stringer tapes. A punching tool has a cutting edge so that, when the punching tool is brought near to the fixed swage, the cutting edge enters a relatively narrow gap between the adjacent edges of the stringer tapes in order to sever a region of the rows of interlocking members coupled to one another only in the limbs on the stringer tape side while the stringer tapes are only placed in the guide channel. An ejector is arranged below the punching tools and, together with the punching tool, can be moved upwards in order to pull the severed interlocking members out of the stitches which fix the interlocking members on the stringer tapes while the stringer tapes are clamped between the pressure pad and the guide plates without pulling the stringer tapes apart laterally.
